PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent o. 507,758, dated October31, 1893.

Application filed December 28, 1891. Serial No. 416.295- (NO modem To@ZZ whom it may concern,.-

Be it known that I, WALTER SCOTT, a citizen of the United States, and aresident of P1ain field, in the county of Union and State of New Jersey,haveinvented certain new and useful Improvements in Printing-Machines,of which the following is a specification.

My present invention relates to printing machines, and has for itsobject the production of copies or packs of sheets, as newspapers,having six, eight, ten, twelve, fourteen, sixteen, or eighteen pages ormultiples thereof. Y

The preferred form of my invention is shown in the accompanyingdrawings, forming part of this specification, in which- Figure 1 is aside elevation of the mechanism, the framework and gearing `beingomitted. Fig. 2 is an enlarged detail view of certain parts. Fig. 3 isan enlarged view of the cutting and folding cylinders in the positionsshown in Fig. 1; and Fig. 4 is an enlarged view of the same after theyhave made onequarter turn from the positions shown in Fig. 3.

The printing machines shown are of the vusual rotary type, and consistof two main printing machines, as A and C, adapted each to perfect a webof desirable width, as single, double or greater width, aud asupplemental printing machine, as B, adapted to perfect a web ofdesirable width. -.The webs perfected by the main machines may be splitinto sections either before or after the printing, when and as may bedesired, or the main webs for each machine may come from two rolls, thesections entering each main machine edge to edge; suitable turners maybe used to superimpose the sections of said main webs to form double,treble, dac., ply webs.

The plate cylinders of each machine are or maybe inked by anysuitableand usualmeans; such means therefore will not be described.

Referring to Fig. l, the .webVV for main machine A is led from a roll(not shown) in any suitable way, as over rollers l, 2, to and betweenthe first plate f cylinder 3 and rst iinpression cylinder 4. The webthen passes under the latter to and over the second impression cylinder5, down between the latter and the second plate cylinder 6. Theperfected web is now led in any suitable way as under roller 7 and overroller 8, to the cutting cylinders 9, 10, which will be moreparticularly described hereinafter.

The web X for the supplemental printing machine B is led from a roll(not shown) in any suitable way, as over rollers 11,12, to and betweenthe first plate cylinder 13, and rst impression cylinder 14. Thence, itpasses under the latter to and over the second impression cylinder 15,between the latter and the second plate cylinder 16. It then passes inany suitable way, as under roller 17 and on tapes 18 to the cuttingcylinders 19, 20, constructed as hereinafter described.

The web Z of the main machine C is led from a roll (not shown) overrollers 2l, 22, to and between the first plate and impression cylinders23, 24, under the latter to and over the second impression cylinder 25.It then passes between the latter and the second plate cylinder 26; fromthence it passes under rollers 27, 28, to the cutting cylinders 29,30,hereinafter described.

As stated above, the webs of one orv both main machines may consist of,or be split into, more than one longitudinal part or section,

and said sections be superimposed to form l two, three, four-ply orgreater ply webs. The instances shown in the drawings are for twosections, where parallel bars 3l, 32, for web W, and 'parallel bars 33,34, for web Z are shown for lsup'erimposing the sections of each. Also asplitter 35 co-acting with a groove in roller 7, and a splitter 36co-acting with a groove in roller 27 divide said webs W, Z, intosections. The number of splitters 35, 36 depends upon the number ofsections ldesired in each case.

The space between roller 17 and cutting cylinders 19, 20, may be bridgedover by any suitable means, as by tapes 18, on rollers or pulleys 38.

The printing machines may be driven at equal speeds by any suitablemeans. means shown consist of a shaft 39 extending The acrosscylinders', 15, 25, and provided with IOO Said shaft 39 isrotatedby anysuitable means V (not shown).

It is understood, of course, that the cylinders, the., of each machineare geared together in the usual manner.

The webs WV, Z, may have transverse lines of paste applied thereto byrevolving blades. Thus web Wr gets lines of paste from blade 46, carriedby arms 47 of shaft 48, and taking paste from a fountain 49. Said shaft48 has a gear 50 by which it receives motion from any suitable part ofthe machine. Web Z receives lines of paste from blade 51, supported byarms from shaft 52, having gear 53, said blade taking paste from thefountain 54. Gear 53 is driven by gearing in any suitable way.

The male cutting cylinder 29 is provided with longitudinal cuttingblades 55, adjacent and following which are suitable sheet retainers, aspins 56. Preferably diametrically opposite blade 55 is the groove 57,adjacent and preceding which in the rotation of the cylinder, is thecreasing blade 58. The female cutting cylinder 30 is provided withsuitably placed longitudinal grooves 59, 60, for co action with saidblades 55, 58, and with grippers 61 for retaining the creased sheets ingroove 60.

The cylinder 9 is provided with cutting blade 62, pins 63, groove 64,and creaser 65, located and operating like parts 55, 56, 57, 58, abovedescribed. Cylinder 10 is provided with suitably placed grooves 66, 67,and grippers 68 corresponding in function with like parts 59, 60, 61,above described. The sheets folded by cylinders 9, 10, and 29, 30, maybe delivered folded further or not as may be desired. For cylinders 9,10, I show a delivery consisting of a roller or pulleys 69 adjacentcylinder 10, tapes 70 ou rollers 69, 71, and another (not shown) andstripping bars 72 having their ends curved about rollers 69 andextending into circumferential grooves 73 of cylinder 10. Foldingrollers 74 (but one is shown) and vibrating creaser blade 75, may foldthe copies taken by the tapes 70. For cylinders 29, 30, I show adelivery consisting of a cylinder 76 adjacent cylinder 30, and havingsuitable sheet retainers as grippers 77, and circumferential groove 78;tapes 79 on roller 80 and others not shown; and guides 81 above tapes 79and extending into said grooves 78. Cylinders 19, 20, are or may bealike. Cylinder 19 is provided with cutting blade 82; a groove 88adjacent and preceding said blade; a groove 84 diametrically oppositesaid blade; and suitable sheet retainers, as pins 85, adjacent andfollowing said groove 84. Cylinder 20 is provided with cutting blade 86,grooves 87, 88, and pins 89, which are located relatively to each in thesame way that the parts 82, 83, 84, 85, are located as described. Allsaid cylinders 9, l0, 19, 20, 29, 30, 76 and roller 69 are gearedtogether (gearing not shown), and have a surface speed equal to that ofthe printing cylinders. Said cylinders are driven by any suitable meansat the described speed, as by gears 90, 91, 92,`

93, connecting the gear of cylinder 30 with that of distributingcylinder 94 of machine C. Cylinder 94 is driven by a gear 95 connectingit with plate cylinder 26.

The operation of the parts is as follows:- The pairs of cylinders 9, 10,and 29, 30, sever full length sheets from the webs W, Z, respectively,While cylinders 19, 20, sever sheets of half said full length from theweb X. The half sheets cut by cylinder 19 from said web are taken to andby cylinder 29, and those cut off by cylinder 20 are taken to and bycylinder 9. With the parts in the positions shown in Fig. 1, the web Wpasses under cylinder 10, up to the grippers 68 which hold the fold. Theend hangs down to about the point 96. Web Z passes under cylinder 29,the end thereof being caught on the pins 56. Cylinders 19, 2O are justsevering a half sheet from the web X, which sheet extends aroundcylinders 20, 9 to the pins 63, on which the end is caught undergrippers 68 of cylinder 10, and one is caught by pins 56. It is to beunderstood that the pins hereinbefore described are mounted in any usualway to be protruded or withdrawn at proper times to take or to releasesheets. 0n further movement of the parts from the positions shown,grippers 68 open, rods 72 strip the sheets from cylinder 10 which sheetsare then run out by tapes 70. The end of the half sheet caught` by pins63 is carried up and the end of web W is caught on said pins. At thetime knife 62 cuts the same, the rear end of the half sheet on pins 63extends over and beyond creaser 65, and is therefore folded or creasedwhen the full length sheet is. In other words, the distance from knife62 to creaser 65 is less than the length of a half sheet, the halfsheets coming close to or against the knife 62. The saine is true oftheknife 55 and creaser 58. The end of web X is taken downward by pins 85.Creaser 58 folds the half sheet in with the web Z, the grippers 6lclosing on the fold and retaining the same in a Well known manner. Asgrippers 6l move down, pins 56 are withdrawn. Next, the knife 55 passescylinder19 by means of groove 84, and pins 56 take the end of the halfsheet, pins 85 being simultaneously withdrawn. At the same time creaser65 and cutter 86 pass each other and the 0pposing cylinders, creaser 65enteringgroove 87 and cutter 86 entering groove 64 in so doing. Next,grippers 6l open to release and grippers 77 close to take the sheets oncylinder 80 as they pass each other. At the same time pins 63 arecarrying the ends of web W and the half sheet downward, and knife 82 iscutting a half sheet from web X, the pins 89 taking the end of the web,and pins 56 having the leading end of the half sheet. Pins 89subsequently deliver the end of the web X to pins 63 in the usualmanner. Pins 63 withdraw to release the sheets about the time grippers68 have tautened the same.

In Fig. 2 is illustrated the manner in which the creaser 58 and knife 82pass each other IOC IIO

and the opposing cylinders at the same time. The manner is the same asthat in which two teeth of meshing gears pass each other. It will thusbe seen that the placing of the creasers 58, 65, following therespective cutters 55, 62, at less than a semi-circumference of thecylinders 29, 9, serves a double purpose; to wit, the creasing in of thehalf sheets and the passing of blades on opposing cylinders.

The grippers, pins, &c., are operated at the described times by suitablecams (not shown).

The subject-matter of this application is shown and described, but isnot specifically claimed in a prior application by me, filed November12, 1891, Serial No. 411,666.

The cutting blades on the cylinders 19, 20, may be removable for thepurpose of associating web X with either of the other webs, and cuttingfull length sheets therefrom, as by cylinders 9, 20, or 19, 29. Thesheets, after being creased by the cylinders 9, 10 and 29, 30, may befolded along said creases subsequently by suitable .means other thanthose shown and described. v

Having thus fully and clearly described my. invention, what I claim, anddesire to secure by Letters Patent, is

1. The combination of two main printing machines adapted to perfect aweb each, a

pair of sheet-severing and folding cylinders for each of said mainmachines cutting full length sheets from said'webs, asupplementalprinting machine adapted to perfect a web, a pair of cutting andtransfer cylinders for severing half length sheets from the supplementalweb, one of said transfer cylinders being adjacent one of the foldingand cutting cylinders of one of said pairs, the other transfer cylinderbeing adjacent'one of the cylinders of the other of said pairs,substantially as and for the purposes described.

2. The combination of two main printing machines adapted to perfect aweb each, a

pair of cutting and folding cylinders for each of said mgain machines,one of said cylinders having oppositely placed cutting and creasingblades, and a groove adjacent one of saidv blades, the other havinggrooves for co-action with said blades and sheet retainers adjacent oneof said grooves, said cylinders cutting full length sheets from saidwebs, a supplemental printing machine adapted to perfect a web, and apair of cutting and transfer cylinders for severing half length sheetsfrom said web and carrying them alternately to said pairs of foldingcylinders, there being a groove adjacent and one opposite veach cuttingblade of said transfer cylinders, one of said transfer cylinders beingadjacent one of the cylinders of one of said cutting pairs, the otherbeing adjacent one of the cylinders of the other of said pairs, wherebyopposing blades pass each other and the adjacent cylinders,substantially as and for the purposes described.
